Vadim Savenkov. Algorithms for Core Computation in Data Exchange. In Data Exchange, Integration, and Streams. Dagstuhl Follow-Ups, Volume 5, pp. 39-68, Schloss Dagstuhl - Leibniz-Zentrum für Informatik (2013)


We describe the state of the art in the area of core computation for data exchange. Two main approaches are considered: post-processing core computation, applied to a canonical universal solution constructed by chasing a given schema mapping, and direct core computation, where the mapping is first rewritten in order to create core universal solutions by chasing it.
